Quantum mechanic with a lot of ontological baggage. I am on the other tweet clients as well.

I warned my students that learning Bell's theorem could be a mentally destabilising experience, but they didn't listen. Now who will be there to pick up the pieces?

@jenseisert By some spooky action at a distance, I'm also teaching it today! They have signed a waiver releasing me of liability if they loose their minds, but also promising not to use the phrase 'spooky action at a distance'.

@dibiagioandrea @Cosmalano I think they also have a much greater chance of making an important contribution following a new program, than in ones which have been around for decades. There's a lot of low hanging fruit, a lot of interest, and the scope (quantum nature of spacetime) is very broad. 2/2

If treated as fundamental, these theories are mathematically inconsistent. The expectation value of the stress-energy tensor of a planet in superposition is the same as two half planets, so the semi-classical Eqns G=8π<T> make no sense 3/

To be fair to Page and Geilker, they wrote their paper at a time when everyone thought the only alternative to quantum gravity was to use expectation values, as in the semiclassical Einstein’s equations or Schrödinger-Newton. 2/

The crackpots will have the last laugh when journal editors stop replying to 𝑜𝑢𝑟 emails because they can’t tell our papers from AI-generated pseudononsense.
I've had a long-standing policy of replying to any "crackpot" emails I get, as long as they sound like they're in good faith, with some encouragement and feedback. Unfortunately I'm now getting a stream of AI-crackpot emails, engaging with which is a complete waste of time...
